New innovations in science and medicine change our understanding of the human body all the time. Starting with the proper foundation provided by an anatomy and physiology course is a stepping-stone in continuing an education in the medical field. Once you have an understanding of the basic systems and functions of the human body, staying up to date on new research will be significantly easier.
Online courses, taken at your own pace, can give you the tools you need to better understand these concepts. Ultimately, your medical career will be reliant on your ability to learn and execute tasks with precision. With a greater understanding of the way the systems of the body interact, a medical professional will be able to successfully determine the problem and conclude a more accurate solution.
There is a range of potential career opportunities for someone with a strong background in anatomy and physiology, from clinical work to laboratory research. These fundamental building blocks of medical science will give you the opportunity to make a difference in the lives of others throughout your career.

When a body is dissected, its structures are cut apart in order to observe their physical attributes and their relationships to one another. Dissection is still used in medical schools, anatomy courses, and in pathology labs. In order to observe structures in living people, however, a number of imaging techniques have been developed.
These techniques allow clinicians to visualize structures inside the living body such as a cancerous tumor or a fractured bone. Like most scientific disciplines, anatomy has areas of specialization. Gross anatomy is the study of the larger structures of the body, those visible without the aid of magnification image below, Figure 1. Microscopic anatomy includes cytology, the study of cells, and histology, the study of tissues. As the technology of microscopes has advanced, anatomists have been able to observe smaller and smaller structures of the body, from slices of large structures like the heart, to the three-dimensional structures of large molecules in the body.
Regional anatomy is the study of the interrelationships of all of the structures in a specific body region, such as the abdomen. Studying regional anatomy helps us appreciate the interrelationships of body structures, such as how muscles, nerves, blood vessels, and other structures work together to serve a particular body region. In contrast, systemic anatomy is the study of the structures that make up a discrete body system—that is, a group of structures that work together to perform a unique body function.
For example, a systemic anatomical study of the muscular system would consider all of the skeletal muscles of the body. Whereas anatomy is about structure, physiology is about function. Human physiology is the scientific study of the chemistry and physics of the structures of the body and the ways in which they work together to support the functions of life.
Homeostasis is the state of steady internal conditions maintained by living things. The study of physiology certainly includes observation, both with the naked eye and with microscopes, as well as manipulations and measurements.
